Question

A wire carrying $I$ is shaped as shown. Section $AB$ is a quarter circle of radius $r$. The magnetic field at $C$ is directed:

• A. Along the bisector of the angle $ACB$, away from $AB$
• B. Along the bisector of the angle $ACB$, towards $AB$
• C. Perpendicular to the plane of the paper directed into the paper
• D. At an angle $\pi /4$ to the plane of the paper

Answer 1

The correct option is C Perpendicular to the plane of the paper directed into the paper

Use Right hand palm rule or Maxwell?s Cork screw rule.

Perpendicular to the plane of the paper directed into the paper.

Hence,

Option $C$ is correct answer.
